BEDDING AND PACKING PURPOSES. v v

1,165,062 all whom'it may concern: Be it known that I, ANDREW C. BORZNER,

' a citizen of the United States, residing at Germantown, in the city and county of 5 Philadelphia and State of .Pennsylvania,

have invented certain new'and useful Im- "p'roveme'nts in the Manufacture from Celluflose-of a Fireproof Substitute for Excelsior for Bedding and Packing Purposes, of

10 which the following is a specification.

" My -inv ention has relation to a manufac- -tured product by chemlcal and mechanical for 'excelsior treatments, as f a substitute for bedding and pacln'ng purposes and to 15' the mode of making such a product from cellulose materials, as paper, cornstalk or tion; and in such connection my present 1nvention rel'atesfirst tot'he method of pro- 20 duction of the "said product; and'second, to,

the'said chemically prepared and mechanically treated fire-proof artificial product,

' the d d purposes.

" The nature, characteristic features and ention will be more fully understood-"from the following detaken in connection with the acshowing ,to. parts,

form adaptedfor the conduct of the method of. producing the artificial fire-proof product p of my said invention. 7

Referring to the, drawings a, is a shredcontainer, in which cellulose material, as paper, cornstalk or other analogous materials are introduced to be converted into a condition for the first chemical action to take In this tank is introduced preferably a hot alkaline solution from a container a.

said solution may be either caustic soda or an inorganic salt, asz'inc chlorid, in the from the tank a into the container 0. This container has introduced into it a solutlon Specification of LettersPatent.

' of preferably ammonium chlorid which is K MANUF ACTimE FROM CELLULOSE or A rmnraoor SUBSTITUTE r03 EXCELSIOR r03 supplied to a batch of pulp'in the propor- I tion of five-(5) partsby weight of the ammonium parts, by weight of the pulp-stock. Of course, it should be understood, that the proportlons above given in both instances may be somewhat varied, "without departing from the spirit or scope ofmy said inven. The last mentioned treatment thoroughly fire-proofs the pulp-mass when it is next compressed into sheet form by chlorid to every hundred (100) a passing through a series of squeezerolls J I and d to bring into a pliable condition for drying in the kiln. e, and when dried, the sheet then passes through fluting-means f, to a series of rotary cutters f, of a shredding machine to :form the thus treated cut sheets into a light fiufiy-like curled condition, for employing then in its fire-proof condition, as a bed-packing product or as a fire-proof general packing product, for various uses, in the applied arts.

- The hot alkaline or other solution is -sup-' plied from the elevated supply tanka -by means of controlled piping a connected with the digesting and separating tank a connection a is arranged from the tanka tothe tank of, with a pump a, therein, and a filter a having a waste outlet pipe a, from the same. Thus canbe, conserved previously employed solutionafter filtering, and supplied to the, tank a, for use again mixed with the solution, of the tank (1 in the digesting'and separating container a and supplied thereto by the controlled piping a to act on 'the contami n'ated waste stock in said tank separate foreign matter therefrom 1n the said tank a. The tank (1 is preferably. interiorlyarranged with af wire-cage a to maintain the stock treated-to free foreignsmatter therefrom. The stock thus freed of its foreign matter is then passed through the controlled pipinga", to the beater container latter by; a trough 12 to the fire-proofing container 'c. This container is provided with a supply pipe'c for the solution, arranged above the same. It then passes by a controlled dischargethroat o to and through a series of squeeze rolls cl and d to a dry1 ng 1 This machine iSpIOVIdGd: with arranged therein and a, to free or-"v as a mass while being 106 b, and from the finally acted upon by aseries of cutters f,

. to thereby bring the thus treated sheets into a curled flufly condition for use, in one form of the artificially produced fire-proof product. It willv be understood that it can be caused to assume finally otherdifl'erent forms for use, besides the one-above men tioned and still be within the scope of my said defined invention. ,It will be also imderstood that other than caustic soda may be employed with good results in separat mg in the first instance the extraneous br foreign matter from the cellulose matter, before actual pulpingof the mass; and further that in the fire-proofing of the pulpmass instead of employing ammonium ch10} rid, an inorganic salt solution may be employed, as silicate of soda, borax 1 or other equivalents thereof, with good results, in

rendering the finally produced product proof-against ready firing, exposed to such influence.

This artificially manufactured product as I i above described in its fire-proof condition is tougher and stronger. than excelsior, it

supplants for packing purposes. It isalso more dense and dependable for use than excelsior, of so highly inflammable-nature, as a packing product. It is far more yielding in quality for packing purposes, because more closely mass ng than excelsior, and more uniform cush oning results can be ob-- tamed inthe apphcation of the same, forbedding purposes.

Having thus describedthe nature and 0b- I jects of my invention, what I claim as new and desire to secure by Letters Patent is-:

1. A bedding and packing product,'con-' sisting of waste paper, cornstalkior the like,

chemically and mechanically treated and reduced to a broken or shredded condition for described. I

2. A bedding and packing product, consisting of waste paper, cornstalk or' the like,

chemically and mechanically treated and rendered fire proof and reduced to a broken or shredded condition for use, substantially asv and for the purposes described.

3. The mode of making a fire-proof prodin treating mat ter derived fromcellul ose with a so'lutlon to remove foreign substance therefrom and to reduce to a pulp-like condition, fire-proofing in a solution and then uct. for bedding and packing, which consists'in treating matter derlved from celluposesdescribed.
